This patchset fixes some issues related to servicing of the
completion queue interrupt.
The major fix is that sensitive hisi_hba structures need to be
locked when free'ing a slot.
Another modification is that the v2 hw completion queue irq is
now serviced with a tasklet, as too much work was being done in
the ISR.

Tested on v2 based sas hardware and the crashes are gone,
